2. Marco Plans to deposit 10,000 into an acct that pays 7% compounded quarterly how many years will he have to leave money on deposit in order to double his money

3. Jane purchased a. Ew home she will finance 120,000 fr 30 years at 6% compounded monthly

Wht Is her monthly payments

How much interest did she pay

1. A person deposits 1000 at the end of every month into acct tht pays 9% compounded monthly if he does this fr a year

What is the amount after last deposit

How much interest did Acct earn 

(a) PMT = 1000, i = 9/1200 = 0.0075, p = 12 

For an ordinary annuity, FV = PMT * [{(1 + ι)^p} - 1] / ι 

FV = 1000 * [{(1 + 0.0075)^12} - 1] / 0.0075  

(b) Interest earned = 12507.59 - 12000 

2. Suppose 5,000 is deposited in and acct left fr 4 years at 8% compounded qurterky

What is value fr n

What is value fr i

Balance aftr 4 years

3. If the initial velocity of a projectile is 128 feet per second, then its height h, in feet, is a function of time t, in seconds, given by the equation

h(t) = −16t2 + 128t.

(a) Find the time t when the projectile achieves its maximum height.

t = sec

(b) Find the maximum height of the projectile.

ft

(c) Find the time t when the projectile hits the ground.

t = sec
